To all whom t may concern/ Be it known that I, HOWARD R. SHEPPARD,

adelphia, Pennsylvania, have invented certain Improvements in Gas andCoal Ranges, of which `the following is a specilication.

My invention relates to certain improvements in combination gas and coalranges in which gas is used for heating theoven, and is a division of anapplication filed by me on the 27th day of August, 1898, Serial No.689,670.

The object of my invention is to improve the construction of the rangeof this character, so that the heating mechanism can beintroduced intothe oven Without interfering With the ordinary construction thereof.

My invention is fully illustrated in the accompanying drawings, inWhich- Figure 1 is a longitudinal sectional View of suflicient of arange to illustrate my invention. Fig. 2 is a sectional plan view on theline a a, Fig. 1. Fig. 3 is an enlarged sectional vieW through thegas-chamber inthe oven on the line b b, Fig. 2. Fig. lis a plan Viewshowing a modification of the arrangement of the oven-heater; and Fig. 5is an enlarged sectional View through the modified form of gas-chambershown in Fig. .4, taken on the line c c.

1 represents the body of the range, 2 is the oven, and 3 is thefire-box, provided with the ordinary grate for burning coal and havingthe usual ash-pit 5.

6 is the iiue passing over the oven from the flrechamber and around theformer to the smoke-stack.

8 is the feed-pipe, connecting the gas-supply pipe at the back of therange With the vertical pipe 9 at the front of the range. This pipe 9communicates with the burner in the oven through the pipes 10 and 1l andwith the burners 19 19 at the top plate through a pipe 6.

Formed in the base-plate 12 of the oven 2 is a gas passage or chamber13, with which the pipe 11 communicates. This passage is trough-'shapedand has a series of lugs 14, on which rests the detachable plate 15,having aseries of perforations 16 therein. This plate is also preferablyprovided With slots 17 at each side, so that the mixture of air and gascan escape from the passage 13 through said perforations and slots intothe oven.

I have shown in Figs. 1 and 2 the passage or chamber 13 having thedetachable form of plate arranged across the center of the oven; but itwill be understood that it may be arranged lengthwise in the oven and atone side of the same, and the notches 17 in each side of the plate maybe omitted, as indicated in the modication, Figs. 4 and 5, or thepassage or chamber 13 may be in the form of a circular ring-A in thecenter of the base-plate of the oven, if desired. 4

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination in a range, of an oven, the bottom ofsaid oven having a recess formed therein, a gas-pipe communicating withsaid recess, a loose burner-plate fitting Within the recess, said platebeing flushwith the upper surface of the bottom plate of the oven,substantially as described.

2. The combination in a range, of an oven, the bottom plate of said ovenhaving an elongated recess formed therein, a gas-pipe communicating withsaid recess, a loose burnerplate fitting Within the recess, said platebeing iiush With the upper surface of the bottom plate of the oven,substantially as described.

3. The combination in a range, of an oven, the bottom plate of said ovenhaving an elongated recess at the center of the plate, lugs projectingfrom the walls of the recess, a loose burner-plate resting Within therecess, and upon the lugs, slots in each side of the burnerplate, and agas-pipe communicating with one end of the recess, substantially asdescribed.
